Speeication of Letters Patent.

Application filed January 8, 1918. Serial N o. 210,902.

To all whom it may concern:

B e it known that LABRAHAM J. SCHULTZ, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Mounting Naps, Caps, and the like upon Hollow Elements; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form la part of this specification.

This invention relates, generally, to improvements in the attachment of naps. caps,

.top-mounts, or knobs to ends of hollow or tubular bed-posts, curtain-rods, and t-he like; and, the present invention has reference, more particularly, to a novel means and method of securing naps, caps, topmounts, knobs, or the like, upon the ends of vhollow or tubular elements, such as bedposts, curtain or portire-rods, or the like, with a view of providing a self-locking nap,

cap, top-mount, or knob, which is simply pushed into position over the end of the lhollow or tubular element. and retained in a positively fixed and non-detachable relation to the end of the said hollow or tubular element.` L

The invention, therefore, has for its principal object to positively unite by means of a self-locking means ornamental naps, caps, top-mounts, knobs. or the like,over the ends of hollow or tubular elements, such as metal bed-posts, curtain poles and-other-rods. in-a most efficient and simple manner, without the use of the'usual pin-screws. orrivets, or,

without soldering, at the same time-providing a method by means of which the various elements mentioned are readily. and quickly united. at a considerable vreduction in Vthe cost of manufacture, and in'a'mostfelfective manner.

`vIn the practice of mountingnaps'caps, ton-mounts, knobs. or the like over the ends of hollow or tubularY posts.lpoles, or rods. as at present, the sheet-metal naps. caps. topmounts` knobs. or the like. are slipped over the ends of such posts, poles, or rods. and are then secured in place hv means of pinscrews, which, it hasbeen found in practice,

soon work loose, and often are lost, thus leaving nthe closing ornamntin an unsccure position upon theend of the post, pole or rod, with the possibility of the loose ornament-,working off andaleo becoming lost. In some instances the said end ornaments are riveted lor soldered to the ends of the posts, poles, or rods, but this entails a tedious operation, with considerable cost in the manufacture, all of which is desirable to avoid; and. the invention has for its further object -to provide a self-locking nap, cap, top-mount, knob, or the like, which by being secured over the end of the hollow or tubular post, pole, orl rod in Athe manner hereinafter more fully set forth, overcomes the objectionable 'features v.mentioned in' the above.v l

Other objects of the present invention not hereinbefore enumerated will be clearly understood from the following detailed descrintion ofthe same.

With the various obiects ofthe present ii'ivention in view., the said invention consists,

primarily, in the novel nap, cap, top-mountor the'like for hollow or tubular posts, `poles or rods, hereinafter setforth; and, the presratentea Jan. 7, 1919.

ent invention consists, furthermore, in the y novel means and method yof uniting the nap, cap, top-mount, knob, orth-e like in its fixed position upon the end of a hollow or tubular bed-post, curtain-pole, rod, or the like, and

in the novel arrangements and combinations v of thevarious devices and parts, as well as in the detailsof the. construction of the said parts, all of which will be more fully described in the following specification, and

then finallv embodied in the clauses of the A claim which are appended -to and which form lan essential part of the said specification.

Thev invention is clearly illustrated in the accompanying drawings, in. which cap Vmounted and secured thereon. accord- Figure lrepresentsin elevation a fragingto `the principlesvof lthepresent inven-,f

tion; Fig. 2-is a verticall sectional representation ofthe said fragmentary portion vof metal bed-post andthe nap or' cap mounted thereon. said view illustrating more particularly the\novel means and method of.`

permanentlyseeuring said nap orV cap upon saidV pos-t; and Fig. 3 is a horizontal section of the same. said section being taken on line 3-,3 in said Fig. 2, lookingin the direction of the arrow w.

Fig. 4 is a Vertical sectional representation, similar tofsaid Fig. 2, of a fragmentary portion of a hollow metal bed-post and a cast-metal nap or cap, provided with a mo-dified form of afiixing or securing means, the nap or ,cap being shown about to be slipped and secured in its fixed position about the end of the metal bed-post.

Fig. 5 represents in elevation a fragmentary-'portion of a cylindrical hollow'post, rod,or the like Aand an ornamental nap or cap mounted and secured thereon according to" the principles ofthe `present invention; 4and Fig. 6 is a transverse lvertical section of the same.

Fig. 7 is a vertical sectional representa- `ltiony of a vportion of a rectangular hollow post or rod and a nap or cap therefor provided with another modified form of securing means, the nap or cap in this view being also shown about to be slipped and secured 'in its fixed position about ,the end of the postor rod.

` Similar characters of vreference are emploved in the saidabove -described views, to indicate corresponding parts.

Referring now especially to Figs. l, 2 and 3 ofthe drawings, the reference-character 1 indicates the end-portion of a rectangular hollow metal bed-po-st, or thelike, the same being provided in its four sides, suitably disposed from the marginal edge 2 thereof, with suitably disposed holes or perforations 3. AThe nap or cap, which may be of any suitable ornamentation, and is' made from sheet-metal, is indicated by the reference-- character 4', andthe same comprises a main member 5 and an ornamental top, as 6, suitably connected therewith, to provide a chamber 7. -The reference-character '8 indicates ya surrounding base-portion, extending inwardly ifrom the lower edge-portion of the said main member 5, and integrally connect- -ed with the several base-portions 8 are upwardly. extending clamping or holding elements 9, of triangular or other suitable configuration, the said clamping or holding` elements being located at ythe marginal portions surrounding the opening 10 and terminating at their upper ends, within the chamber inslightlv inwardly extending retaining lingers or holding tongues, as 11. In order 4to 'positively secure the said nap, cap, topinount. or the like upon the upper end-portion of the said bed-post, or lother hollow member, the 'end-portion 2 is inserted in the correspondingly formed opening 10 of vthe main member, and between the several upwardly extending clamping or holding elements` 9, until the respective holes or perforations 3 are brought opposite to and in registration with the respective retaining fingers vor holding vtongues 11 of the elements '9, the spring-like action of the said elements 9, as will be evident, causing the said fingers or tongues Ythe like, yas shown 'in Fig. 2 of the drawings, so that thereby the .said nap, cap, topmount or the 1li-ke, when fixed in its locked Furthermore, the disposition, `is maintained `in such position against movement-l upon the end of the post,

to prevent wabble or rattle of the assembled parts. i y

Vhile in Figs. 1, 2 and 3 of the drawings,

the post-like element 1 and the nap, cap, or

top-mount are vshown of a square or foursided cross-section, it will be clearly understood that these elements may be of any other desired and suitable polygonal crosssection, the holes or perforations '3 4andthe holding or clamping members A9 being varied accordingly. i

1n Fig. 4, of the drawings, I'have shown the post-like element with a cast-metal nap, cap or vtop-mount, indicated by the reference-character 13. In `this case, the hollow or chambered portion 111 of said nap, cap, or top-mount, has extending inwardly lfrom the walls 15 suitably disposed projections or teats, `as 1G, adapted to be forced into the hOleS OI pelforations 3 of the post-like member or element, so as to secure the said parts in their positively assembled relation against accidental separation, without the *use of pin-,screws or solder, as will be clearly evi- .i

holes or perforations 18, the reference-character 19 indicating a suitably shaped ornamental nap lor cap therefor, the latter comprising a cylindrically formedmain member 20 provided with an ornamental top or dome 21 suitably conn^cted therewith, to `provide a Achamber 22. Extending upwardly and inwardly from the lower marginal edgeportion 23 of the said member'20, and' integrally onnectedjtherewith, are clamping or holding elements 24 which terminate Aatth'eir upper ends, within the chamber v22 vin slightly inwardly extending retaining 'fingers yor holding "tongues, `as 25. `The Inap or Cap, mounted upon the end of the tubular post 17, in fthe manner of the construction vset forth in Figs. 1, 2 and 3 ofthe drawings,

' by slipping said nap or cap down over` the end of the tube, until the retaining fingers of the construction just described, is

y'or holding tongues 25 register with the holes -or perforations 18, and spring into :the said holes or perforations sufficiently so as to maintain a positively locked engagement of the nap or cap with the said tubular post or element 17 In Fig. 7 of the drawings, I have represented an assembled arrangement of ornamental nap or cap, similar to that illustrated in Fig. 2 of the drawings, except that in lieu of the triangular clamping or holding elements 9 shown in said construction, thtX base-portion 8 of the main body 5 of the nap or cap has an upwardly and inwardly extending tubular portion, as 26, slightly marginally curved or inwardly bent, as as 27, said tubular portion 26 being provided with pressed-out projections or teats, as 28, which are adapted to register with and brought into holding or loked engagement with the holes or perforations 3 in the post or tube-like element 1, as will be clearly understood from an inspection of said Fig. 7 of the drawings.

From the foregoing description of my present invention, and from an inspection of said Fig. 2 of the drawings, it will be clearly seen, that the various parts are easily and quickly brought into their assembled and positively united relation, without the use of pin-screws, rivets, or solder, as heretofore, so that thereby the parts are more quickly united, and the cost of the manufacture greatly reduced, because the uncertain operation of inserting a clenching or ri-vcting tool within the assembled tubular or hollow members is clearly avoided.

I am aware,`therefore, that some changes may be made in the arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, without departing from the scope of the present invention as described in the said specification, and as defined in the clauses of the claim which are appended to the said specification. Hence, I do not limit my present invention to the exact arrangements and combinations of the various devices and parts as described in the said specification, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.

I cla1m:-

1. In combination with a hollow element, as a metal bed-post, rod or pole, provided with perforations, an ornamental nap having a chambered portion adapted to be mounted upon the end of said hollow element, and holding projections connected with said nap and extending from the inner surface ther of into the chambered portion of said nap, said projections being adapted to be forced into holding engagement with the perforations in said hollow element.

2. In combination with a hollow element, as a metal bed-post, rod or pole, provided with perforations, an ornamental nap having a chambered portion adapted to be mounted upon the end of said hollow element, clamping elements connected with said nap, said clamping elements extending upwardly into the chambered portion of the nap, and engaging fingers connected with said clamping elements, said lingers being adapted to be forced into holding engagement with the perforations in said hollow element.

3. In combination with a hollow element, as a metal bed-post, rod or pole, provided with perforations, an ornamental nap comprising a main body and a dome forming a chamber, a marginal base-portion connected with said main body, said base-portion providing an opening for mounting said nap upon the end of said hollow element, marginal clamping elements connected with said base-portion and extending into the chamber of said nap, and engaging lingers connected with said clamping elements, said fingers being adapted to be forced into holding engagement with the perforations in said hollow element.

In testimony, that I claim the invention set forth above I have hereunto set my hand this 2nd day of January, 1918.
